To all whom it may concern:

Be it known that I, EMIL L. CLAUS, a citizen of the United States, andresident of Milwaukee, in the county ofMilwaukee and- State ofWisconsin, have invented certain new and useful Improvementsin CombinedBurner Structures for Gas-Stoves; and I .do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to new and useful Such cooking stoves are usuallyprovided with a plurality of main burners and a relatively smallsimmering burner adapted to supply a small amount of heat for certaincooking operations. In addition to economy of manufacturing costs, avery important consideration in commercial structures of this characterresides in the amount of space taken up within the confines of the stoveby the burners and their valve connections .with the supply pi e.extending along the front of the stove. en a considerable number ofburners are emplo ed in connection with a simmering burner, it isdifficult to procure a desired spaced relation of the supplyvalves forthe various'burners.

It is therefore primarily the object of my simmering burner with thestructure of one of the main burners of'the stove, to pro cure economyin manufacturlng costs and to also dprocure an increased free spacewithin the ticularly, it is an important object to coinbine the controlmeans for both the main' and simmering burners in a single valvestructure, to thus reduce the number of valve units along the mam supplypipe of the stove, permitting an increased freedom of manipulation ofthe valve and lessening the danger incidental to accidental opening ofthe valves. 7

A further object residesin he provision of an arrangement wherein t esimmering burner and one of the main burners of the stove may beembodied in a single casting to thus avoid the necessity of providingan'ad-' ditional casting for the simmering burner, and to procure anecgnomy of space which would otherwise be mering burner.

A still further object resides in the pro vision of a valve structurewhich is 0p'er-' Specification of Letters Patent.

ative to supply gas to either the simmering burnerpr its associatedmaimburner, and which in certain instances may be manipulated to supplygas simultaneously to both burners. v

In my co-pending, application for patent,

means is disclosed for, automatically actuatmg igniter torches forselective burners. upon opening the supply valves for such burners. Inthis connection it .is a still further obj ectto automatically actuatean igniter torch for both the simmering and main burners when thecombined valve structure is-operated to supply gas to either of saidburners.

'With the above and other objects and advantages in view, which will beapparent as the description proceeds, my invention resides in the novelfeatures of construction, combination and arrangement of parts ashereinafter more particularly described and defined by the appendedclaims.

in the pipe-for its inlet portion 7 threaded supplying both the mainburner and the si-mmering burner. 1,

As shown in Fig. 1, these burners are preferably embodied in a singlecasting com- .prising the usual duct 8 for conveying commingled air andgas, this duct being enlarged in substantially cup shape to form themixing head 9 adjacent the valve, and having its other end merged intoand communicating with the hollow annular burner head 10 having radialfins 11 provided with the burner jet openings. In carrying out myinvention, the duct 8 is provided preferably adjacent one side with alongitudinal partition 12, which is extended into the burner head anddirected laterally to cut oi the adjacent fin, designated specificallyat 11', from the major portion of the burner head. This partition isalso extended into the mixing head 9 to divide off a correspondingportion ofsaid mixing head. The valve casing is provided with a maindischarge nipple 13, projecting centrally into the mixing head 9 in theusual'manner, and has a lateral extension 14 from which a nipple 15extends for projection into the portion of the mixing head divided offby the partition 12. The usual control valve plate 16 is rotatablymounted on the end of the air mixing head 9, being'apertured at 17 toexposethe mouth of the dividedoff portion of the head in the variousadjusting positions of the valve plate.

.Thus, when gas is supplied through the main burner nipple 13, it'willmix with air in the head 9 and pass through the major division of theduct 8 for ignition at all of the jets of the burner head with theexception of the jets of the fin or portion 11. When gas is supplied tothe simmering supply nipple 15, it will mix with a sufficient quantityofa'ir and pass through the minor divisionof the duct 8 for ignition atthe jet of the fin 11 to thus supply sufficient heat for the desiredpurposes of a simmering burner. It is noted that the passageway of thedivided off portion of the duct 8'is slightly enlarged within the burnerhead to facilitate proper admixture of air with the as. g Describing nowthe valve structure shown specifically in Figs. 2 to 5, it is noted thatthe valve casing 6 is provided with a torch supply port 18, preferablylocated under the simmering supply extension 14, and connected b atube-19 with a torch head 20 pre'ferab y of the type shown in my saidcopending application for patent, this torch head being adapted todirect a torch toward the burner head to ignite either the main burneror simmering burner section thereof. The usual slightly tapered valvemember or key 21 is rotatably mountedin the casing,

being held in seating position by a spring 22 coiled on its lowerprojected end portion and exerting pressure against'the bottom of thecasing 6 and against a washer secured by a screw 23 threaded in thelower portion of a Well 24, extending through-the major portion of thevalve member, the lower-portion of thewell being shouldered to seat adisk 25 of lead or other packing material whereby to effectively sealthe lower portion of the well. The inlet port 26 of the valve casing isinclined upwardly'in the portion 7, while the main burner supply port27is inclined downwardly in the discharge nipple 13, said ports thuscommunicating with the valve member at different elevations, and thevalve member is provided at said elevations with passages 28communicating with the well whereby when the ports and passages are inregistry, free flow of gas will be provided through the valve for themain burner, movement of the valve to effect this openposition beingprocured in the usual manner, wherein the handle 29 of the valve memberis swung in a clockwise direction from a closing position substantiallyparallel to the main supply pipe 5 to a position wherein the handlemember extends transversely of the supply pipe, this open position ofthe valve for the main burner being illustrated in the drawin The valvemember is also provided with a torch supply passage 30 communicatingwith its well at the plane of the torch supply port 18,whereby as setforth in my said co-pending application for patent, a torch flow of. gaswill be procured for the torch head upon movement of the valye memberslightly past open position for the main burner. The valve casing isalso provided with bypass ports 31, controlled by a valve screw 32, forsupplying pilot flow of gas to thetorch head.

Gas is supplied to the simmering burner extension 14 through a passage33 communicating with the well at the plane of said extension, the valvebeing rotated from closed position in a counter-clockwise direction toprocure registry of this passa e 33 with theextension 14. A torch flow 0gas upon this registry is procured by a passage 34 extendin oppositelyfrom the passage 30 of the va ve member in the plane of the torch supplyport 18, the-valve member being rotated slightly past its open positionfor the simmering burnerto effect this torch flowi An exceedingly.simple and readily operated valve structure has thus been providedwhereby upon turning the handle in one'direction from a closedor'neutral position, the main burner will be supplied with gas andignited, and upon turning the handle in the other direction from closedor neutral position, the simmering burner will be supplied with gas andignited, a .slight retrograde movement of the valve member in either inlstance serving to shut ofi' the torch flow of as and maintain fullsupply of gas to either urner. l-It is noted that the various ports ofthe valve structur e are adapted for registry in four different planes,whereby accidental registry of the ports is avoided, and

by disposing the main burner passa es28 of the valve member in .the twointeme iate registering planes, undesired registry of said members isprevented when the valve memher is swung to torch supply position forthe simmering burner.

' In'Figs. 6 to 10, a modified valve structure I is shown wherein thevarious supply operations are more distinct, to lessen the possibilityof accidental opening of undesired ports, and also to provide forslmultaneous supply of gas to both the mainburner and the slmmeringburner. In this structure, the inlet port 26* and the main burner port27 are disposed in a common intermediate plane, the simmering supplyport 14 and flash supply port 18 beingdisposed respectivelyabove andbelow said common plane.

A tapered, valve sleeve is rotatable in the valve casing, and themainvalve member or key 21' is rotatable in this sleeve, being provided witha well 24= as heretofore described.

The main valve member is provided in its.

intermediate portion with opposed passages 36 communicating with itswell and adapted to aline with the ports 26 and 27, and

- the valve sleeve is provided with passages v 37 also adapted toregister with the ports 26* and 27, whereby when all of the ports and Ipassages are in registry, flow of gas is provided for the main burner.

register with the inlet port 26* and with a passage 39 adaptedtoregister with the simmering port 14, together with a passage 40 M in theupper portion of the valve member.

The valve memberQl is provided with a handle 29*, and the valve sleeveis provided with a handle 41 movable in a plane unde the first namedhandle.

Thevdrawings illustrate the open position of the valve for the simmeringburner alone, in this position the handles 29 and 41 extendingtransversely of the supply pipe.

Thevalve sleeve in thisposition shuts off the main burner port 27, theinlet port 26" being open by registry of the sleeve passage 38' and thepassages 39 and 40 are in registry with the simmering supply port 14".In the closed position of the valve whereby, as isusual in gas stoves,the handles project substantially parallel to the main supply pipe 5,the opposed passages 37 of the valve sleeve are disposed in registrywith the main ports 26 and 27, but the passages 36 of the 'valve'member21 are disposed out of registry. Thus, to procure flow of gas to themain burner alone, it is merely necessary to grasp the handle 29' andswing the valve The valve sleeve. is also provided with a passage 38adapted to member in a ClOCkWlSe dlrectlon to a position 1 that uponturning movement of the valve reason of the differential peripheralareas of the valve member and sleeve.

To procure torch fiowof gas in connection with these aforedescribedvalve movements, the lower portion of the valve member iS. provided witha passage '42 adapted to registransverse of the supply pipe,- it beingnoted member, the sleeve will remain stationary by ter with the torchsupply port 18 when the valve member is swung slightly past its fullregistering position with the main valve. The valve sleeve is alsoprovided with passages 43 which register with the torch supply port l8vwhen the sleeve is'in full closing position of the valve or in aposition of the'valve which supplies the'si mmering burner alone.

Although the present valve is capable of other use as will be laterdescribed, it' is desired to point out that by the afore describedstructure, I have provided an arrangement wherein opening movement forsupplying eitherthe main burner or the simmering burner may be procuredby rotating either one or both of the handles through a substantiallyquarter rotation and in the conventional clockwise direction, it beingnoted that the controlling movement for supplying the main burner iscarried out in entirely conventional manner.

the simmering burner, and to this end, the valve sleeve, is providedwith a port 44 which is adapted to register with the sim- The presentvalve structure embodies also an arrangement for supplying gas simul-.'taneously to both the main burner and mering. supply ports 14 when thevalve sleeve is rotated through 'a half-circle from its full closingposition, and the sleeve isialso' provided with a passage 45 adapted toregister with the torchsupply port in this position of the sleeve.Hence, when the sleeve is swung to this extreme position, it affordsfree passage through all of the ports of the valve and when the valvemember is swung to open position, gas is supplied through the main andsimmering ports 4 and may also be supplied through the torchsupply port.The valve'sleeve is limited to.

' of the main burner head, said supply duct being provided with alongitudinal partition 12 defining a passageway commumeating with thepipe 50 and with the'sim- .mering supply nipple 15 ofthe valve.

While I have shown and described 'preferred embodiments of variousphases of my invention, to meet differing'desired conditions of use, itwill be appreciated that still other embodiments involving variouschanges and modifications of structure may be employed to meet otherconditions of use and manufacture. without departing in any manner fromthe spirit of my invention as defined by the accompanying claims.
